Sidi London Insoles

Yes, the Sidi London insoles are designed to be compatible with most standard cycling shoes. Since they are a drop-in replacement, you can simply remove your existing stock insoles and swap them for these.

They provide a noticeable layer of thermal insulation, so they are slightly thicker than standard summer insoles. If your cycling shoes already have a very tight, race-oriented fit, you might find them snug, but for most riders, the added warmth is worth the minor adjustment.

Yes, these insoles are designed to be trimmable. You can use your current shoe's insole as a template to cut them to the exact shape and size needed for your specific footwear.

While their primary purpose is thermal regulation, they do offer more cushioning and structure than the thin, flat liners that come standard in many cycling shoes. They provide a comfortable, supportive base, though they are not a replacement for custom orthotics if you require specific medical-grade arch correction.

These insoles are engineered for high-level thermal retention and are excellent for typical winter riding conditions. However, for extreme sub-zero temperatures, they work best when paired with high-quality winter cycling socks and windproof shoe covers.
